APPARATUS FOR REGENERATING EXHAUST-STEAM.

SPECIFICATION formingpar't of Letters Patent No. 619,1 1'9, dated February 7, 1899.

Application led September 21, 1898. Serial No. 691,485. (No model.)

To LZZ whom it may concern:

Beitknown that I, HUGH J. BARRON, a citizen of the United States, residing at the city of New York, in the county and State of New York, have invented certain new and useful 'Improvements in Apparatus for Regeneratin g EXhaustSteam, of which the following is a full, clear, and exact specification.

My invention relates to improvements in steam-engines, and has for its object to provide an apparatus for regenerating exhauststeam of the type disclosed in United States Letters Patent No. 607,582, granted to me July 19, 1898; and my present invention has for its object more particularly to provide an apparatus wherein only a portion of the live steam need be diverted and employed to attain the desired result, and thus enable me to more economically revaporate andreutilize the exhaust-steam discharged from the engine and at the same time generate new steam by contact or association with the live steam maintained intermediate the boiler or main generator and the apparatus or auxiliary generator. i

The object above set forth I am enabled to attain by means of my invention, which consists in the novel details of construction and the combination, connection, and arrangement of parts, as hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, wherein like letters of reference indicate like parts, Figure l is a front view showing a boiler and engine and an apparatus constructed according to and embodying my invention in combination therewith. Fig. 2 is an enlarged end elevation of the apparatus disconnected from the boiler and engine, and Fig. B is a top or plan View thereof.

In said drawings, A designates a boiler of ordinary construction, B an engine, and C the apparatus or auxiliary steam-generator.

D D denote cylinders supported in vertical positions upon a suitable base D2.

E, F, G, and H denote pipes arranged in the order named', beginning at the top of the cylinders D D and communicating therewith, and E' F' G' H' and E2, F2, G2, and H2 denote valves arranged in the pipes E, F, G, and H, adjacent to the cylinders D D', respectively,

said valves having outwardly -projecting stems, to the ends of which are respectively secured levers e' f' g' h e2 f2 g2 h2.

l denotes the main steam-pipe, leadingr from the boiler A to the engine B, having a pres sure-reducing valve I', arranged therein. From said main steam-pipe I intermediate the boiler A and the reducing-valve I', extends an inlet-pipe I2, which is connected between the cylinders D D' to the pipe F.

J denotes the outlet-pipe, which is connected at one end to the pipe G, connecting the cylinders D and D', and at its other end to the main steam-pipe l, intermediate the reducing-.valve I' and the engine B. K denotes the exhaust-steam pipe leading from the engine B and connected between the cylinders D and D' to the pipe E, said exhaust-pipe K having an outlet K' therein, a diaphragm K2 connected thereto, and a connecting-section K3 uniting the same with the reducing-valve 1' of the pipe I, whereby a uniform pressure is maintained in the receptacles D D', and L the condensation and vapor pipe,which is connected to an exhauster L', and L2 denotes a pipe connected to the exhauster L and the pipe J.

L3 denotes a branch pipe leading from the condensation and vapor pipe L to the suction part of the forward cylinder of the pump O, as seen in Fig. l.

M M' denote brackets the ends of which are secured to the cylinders D D', the bracket M being secured between the sets of valves E' E2 and F' F2 and the bracket M' between the sets G G2 and H' H2. Upon the outer surfaces of said brackets M M', about midway of the distance between the cylinders D D',

are provided studs mim', upon which are mounted wrist-plates N N', respectively, the wrist-plate N being provided with a long depending bent arm 'n and the wrist-plate N provided with a shorter depending arm n', and upon the rear sides, adjacent to their peripheries, said wrist-plates N N' are provided with pins t' z", respectively, and jj de note links having their outer ends pivotally secured to the ends of the valve-stein levers and their inner ends similarly secured to the wrist-plates N N by the pins t' i'.

O denotes a duplex direct-acting steampum p provided with a bracket 7c, upon which are pivotally supported the levers P P', the lower ends of Which levers are respectively connected to the piston-rods o of the pump, and adjacent to one end of the pumpv O are provided bearings Q Q, Within which is supported a rock-shaft R, having a loose sleeve R thereon. Upon the rock-shaft R is iixed one end of the lever S, the other end of which is connected by a link T With the arm n of the Wrist-plate N, and fixed also upon said rock-shaft R is one end of a lever U, the outer end of Which is connected by a link V with the upper end of the lever P of the pump O, and upon the sleeve R is fixed one end of the lever S', having its other end connected by a link T with the arm n' of the wrist-plate N', and U' denotes a lever having one end xed upon the sleeve R and its other .endconnected by a link V to the upper end of the lever P' of the pump O.

To one cylinder of the pump O is connected boiler, andg denotes a valve arranged in the" pipe 0' intermediate the ends of the loopsectionA O3 for causing the water to pass through said loop-section. To the other cylinder of the pump O is connected the coldwatcr-supply pipe X, which is connected to the valves E' E2, whereby cold Water is admitted to the cylinders D D' for the purpose of reducing the temperature of any steam which may remain therein before or simultaneously With the admission of exhaust-steam to said cylinders D D.

The operationv of the apparatus isas follows: If We assume the apparatus C to be in theposition indicated at Fig. 1 and the cylinder D to contain exhaust-steam, the live f steam from the boiler, with a pressure, for example,of one hundred and twenty-five pounds, will be conducted from the boiler through the main steam-pipe I, and after passing through the reducing-valve I" be supplied to the engine at, say, a uniform or constant pressure of one hundred pounds. At the same time, however, the excess of steam or a portion thereof maintained in that section of the pipe Iy intermediate the boiler'and the reducingvalve I' Will bediverted and conducted to the cylinder D' by the pipe I2, pipe F, and valve F2, absorb a charge of hot Water conducted to said valve F2 by the pipe O, convert the same into steam, and thence pass into the cylinder D' and unite with the exhaust-steam contained therein, and thereby regenerate the same. The regenerated exhaust-steam, with a. pressure of about one hundred and five pounds,will thence pass out of the cylinder D' by way of the valve G2, pipe G, pipe J, and into the main-steam-pipe I, intermediate the reducing-valve'I', and unite with the steam passing therethrough and to the engine. At the `E2 H2 of thecylinder D'.

same time the exhaust-steam from the engine will be returned to the cylinder D through the exhaust-steam pipe K, pipe E, and valve E', and at about the same time or shortly before the admission of the exhaust-steam 'to said cylinder D a charge of cold Water Will be sure and facilitate the admission of exhauststeam to said cylinder D at the reversal of the valves. The condensation, if there be any, or any hot or cold Water which may remain unevaporated in said cylinder Will be conducted therefrom by the valve H' and pipe H :to the hot-Water cylinder of the pump O, and I thence again supplied partly to said cylinders D D' by the pipe O' and to the boiler by the branchpipe O2, and simultaneously therewith vuncondensed vapor remaining in said cylinder Will be taken by the exhauster L in sufliicient quantity to maintain a normal back `'pressure in the apparatus, Which vapor thus Withdrawn Will thence be forced through the ,pipe L2 into the section of the main steampipe I intermediate the reducing-valve I' and the engine. It will be observed that at this ,period or stage of operation steam under high pressure will be supplied to the engine B by the `main steam-pipe I, pipe I2, cylinder D', and

pipe J, While exhaust-steam will be conducted through the main exhaust-pipe K, pipe E, and into the cylinder D, and the unevaporated lhot and cold Water and condensation, if there vbe any, conducted from the apparatus bythe pipe L and pulnp O and recirculated and the funcondensed vapor taken bythe exhauster L and supplied to the engine. As soon as the operation above described has taken place the Wrist-plates N N will be partially rot-ated "by the action of the steam-pump O, communicated thereto by the intermediate mechanism, comprising the levers S S', links V V', vlevers U U', and links T T', and cause the valves F2 G2 of the cylinder D' and the valves `E' H' of the cylinder D to close, and open the valves F' G' ofthe cylinder D and the Valves Hereupon steam from the boiler will pass through the main steam-pipe I, pipe I2, pipe F, valve F', and into the cylinder D and in so doing receive at the valve F a charge of hot Water from the }pipe O, absorb and convert the same into steam, and thereupon unite with the exhaust- .steam contained in said cylinder Dand regenerate the same, and thence pass out of said cylinder'D through the pipe G, valve G', pipe J, and through the main steam-pipe I to the engine B. The exhaust-steam now being rel turned from the engine to the cylinder D' l.through the exhaust-pipe K, pipe E, and valve F2, and at about the same time or shortly before the exhaust-steam enters the cylinder D',

TOO

IIO

a charge of cold Water is taken from the pipe X at the valve E2 and sprayed Within said cylinder D' to reduce the temperature of any live steam Which may have remained therein from the previous cycle of operation, and thereby facilitate the entrance of exhauststeam into said cylinder, the hot and cold Water admitted to said cylinder Which may remain unevaporated or the condensation, if there be any, being conducted from the apparatus by the pipe I-I, pipe L, and recirculated and the uncondensed vapor taken by the exhauster L' and supplied to the engine B, as hereinbefore described. Immediately thereupon the valve mechanism will be again shifted and assume the initial position and the operation rst above described repeated, and so on, the inlet-valves F F2 being arranged to close a triiiein advance of the outlet-valves G' G2. However, the precise manner of operation of the valves must be determined by actual experiment in each case, and I do not Wish to limit or confine myself in this respect, nor do I wish to confine myself to the form of exhauster shown. These I consider mere details which may be varied Without departing from the spirit of the invention; but
